ANSWER:

There are 600 boys and 800 girls.

SOLUTION:

We are given the following facts:

  • The total number of students is 1,400.
  • The ratio of boys to girls is 3:4.

We express this as a partitive proportion.

» Solve for x.


  • \sf 3x + 4x = 1400

  • \sf 7x = 1400

  • \sf x = (1400)/(7)

  • \sf x = 200

Now we to solve for the number of boys and the number of girls.

» Number of boys:

  • =
    \sf 3x
  • =
    \sf (3)(200) =
    {\boxed{\sf 600}}

» Number of girls:

  • =
    \sf 4x
  • =
    \sf (4)(200) =
    {\boxed{\sf 800}}

Thus, there are 600 boys and 800 girls. The sum of these is the total number of students in Shiloh Middle School.

HOPE IT HELPS!
